British Airways (BA, London Heathrow) and American Airlines (AA, Dallas/Fort Worth) are trimming schedules over the 2025 northern summer because of issues affecting their B787 aircraft.

British Airways is pausing its London Heathrow - Abu Dhabi International route between London Heathrow and Abu Dhabi between March 30 and October 25, 2025, because of supply chain challenges impacting the production and repair of the Rolls-Royce Trent 1000 engines on its B787s.

“We’re disappointed that we’ve had to make further changes to our schedule as we continue to experience delays to the delivery of engines and parts from Rolls-Royce, particularly in relation to the Rolls-Royce Trent 1000 engines fitted to our B787 aircraft,” a BA spokesperson told ch-aviation. “We’ve taken this action because we do not believe the issue will be solved quickly."

Rolls Royce is experiencing problems sourcing some raw materials and parts used to make the Trent 1000 engines, reducing its output of new engines and also delaying repairs to in-service engines.

British Airways has previously rejigged its schedules to accommodate these issues. On or around March 30, the airline is suspending its flights to Kuwait and Dallas/Fort Worth and is reducing its 2x daily service to Miami to daily. It has also axed its London Gatwick - New York JFK over the current northern winter and delayed the restart of flights to Kuala Lumpur International.

"We continue to work closely with Rolls-Royce to ensure the company is aware of the impact its issues are having on our schedule and customers, and seek reassurance of a prompt and reliable solution," the BA spokesperson added.

Rolls-Royce did not respond to a request for comment.

On the other side of the Atlantic, American Airlines is suspending services on the Miami International - Paris CDG route in May 2025, delaying the start of the Chicago O'Hare to Paris Charles de Gaulle route from April to May, and trimming frequencies on the Miami - Buenos Aires Ministro Pistarini route from 3x daily to 2x daily because of B787 delivery delays, as reported by The Points Guy.

An American Airlines spokesperson told ch-aviation that the carrier "remain(ed) committed to mitigating the impact of these Boeing delays while continuing to offer a comprehensive global network.”

American Airlines operates a fleet of fifty-nine B787s, including thirty-seven B787-8s and twenty-two B787-9s. It also has another thirty B787-9s on order. Of the existing B787 fleet, the ch-aviation fleets module indicates three B787-8s and one B787-9 are presently out-of-service.

British Airways operates eleven B787-10s, twelve B787-8s, and eighteen B787-9s. The airline has a further seven B787-10s on order. Currently, one B787-10, three B787-8s, and three B787-9s are on the ground.
